IMPROVEMENT IN FARMERS BOILERS.

Specification forming part of Letters Patent No. 144,890, dated November 25, 1873; application filed November 21, 1872.

To all whom t may concern:

Be it known that I, PAsoEAL GoLvIN, of Pecatoniea, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Heaters; and I do hereby decla-re that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l is a perspective view of my improved heater with a portion of the outer shell broken away to show arrangement of the fuel, smoke, and draft ues. Fig. 2 represents a modification of the invention, and Fig. 3 is a transverse horizontal section of Fig. 2.

Similar letters of reference denote corresponding parts in all the gures.

The object of the invention is to construct a cheap, effective, convenient, and durable heater for the purpose of cooking and steam'- ing food, and heating waterl for various purposesupon the farm; and to this end it con sists in constructing the combustion-chamber in circular form, with feeding, draft, and smoke flues rising vertically from opposite ends of the combustion chamber to such height as will permit said chamber to be submerged, in part or in whole.

In Fig. l, A is the outer shell, and A the inner one, which, with a suitable top and bottom, inclose an annular space or water-tight compartment. In practice, I usually prefer to mount this shell upon feet et, three or more in number, to keep it elevated a little from the bottom of the tub or vat, for a purpose which will soon be explained. B is the fuelilue, which rises from the combustion-chamber. C is the draft-line, divided from fuel-Hue B by a partition, B', which extends nearly to the bottom of the fire-chamber. D is the smoke-flue.

The wall of this flue, which is next to the draftflue', extends to the bottom of the heater, and, by preference, I make the opposite side to project some distance below the upper surface of the tire-chamber in order to compel the heated currents to descend to the lower part of the chamber, and thus render them more effective. In Figs. 2 and 3, E is the outer shell, and F the inner one, forming an annular space, through which the heated products of combustion are ca-rried in the direction indicated by the arrow. F1 is a flange, rigidly attached to the inner shell, and serving to form the top ofthe annular space between the two shells. G is a par-y tition secured in place by angle-irons c, which are riveted to the inner wall F. The small space thus inclosed serves as a draft-Hue, and, when the partition is burned out, it can be readily slipped out and a new one put in. I is the lid, a portion of which, corresponding to the space inclosed by partitions G for a draft-flue, is cut away so as to aiford ready access for a current of air. H is the smoke iiue or pipe.

I generally form one end ofthe shell F into a scroll, as at F2, and make it serve as a support for the pipe H. When preferred, the cover I may be cut to t the inside of shell E, and rest upon flange F1.

It will be readily seen that when either the Shell F, partition G, or pipe H are burned out they can be easily replaced, as they are all detached from the outer shell E.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

I. In combination with the inner shell F, the partition G and flanges or angle-irons e, substantially as described.

2. In combination with the outer shell E, the inner shell F having one end thereof formed into a scroll, F2, and serving as a support for the pipe H, substantially as described.

This specification signed and witnessed this 2d day of October, 1872.
